Sith Battlemaster, Obelisk Prelate, or Krath Archpriest (commonly known as Equite 2 or EQ2) is the tenth rank in the Dark Brotherhood, which is awarded after demonstrating above and beyond performance as a 1st level Equite. At this rank members may request a Custom Lightsaber.
It is the second rank in the Equite class, the second step down the path to Dark Side Adept.
Promotion past this rank is determined by your Clan Summit when a promotion is warranted based on performance and activity.
Upon promotion by your Clan Summit, you will reach one of three Equite ranks based on your Order.
